If you only use the app on your phone to fly it, does it work then? If so could be an issue within the controller. You can check the antenna internally to see if it has been rubbed and damaged by the phone holder swinging out.
Hi, I'm Brett.
Just received the SG906 Pro2. Used to Race electric trucks many years ago and now wanting to get back into the R/C world.
Had a toy quadcopter about 3-4 years ago and it went swimming so just now getting into it again.
Hope to learn a lot from you guys and gals, kor as we say...
